After seeing some weird darks on day 6 -999 temp data sets I wanted to see if I saw the same thing on the other dark data sets. Each graph below is for one dark file. All the dark files (d*.mat) for all DAYSXX are plotted. The title show the day and filename and the number of darks in the day X dir. The title above the image is the int time and temperature for the dark. The three graphs on the left compare the same pixels put one is from a line going north and south on the image and the other is going east to west. The three panels are the three pixels (100, 500 and 900). The red line is a dark at pixel X and goes across the tracks (red lines in the image going east to west). The blue line is the dark at the same pixel but in the direction is north to south in the image (blue lines), this is the wavelength direction. The image shows you the big picture, with the blue and red lines showing where the blue and red line on the three panels came from. Make sense?
Most of the data below look Ok. The day 04 darks have some light tracks on them. But they are VERY small and only really visible in the images. A few of the day 5 images also had tracks in the images. They are also VERY small. Day 06 is the interesting data set. The first darks which were collected with the temperature controller on and the instrument was nearly at -40C but the instrument records the temperture as -999. For the first file there is a large sawtooth pattern in the darks in the wavelength direction but in the track direction the data look more normal. On the second file the sawtooth pattern is mainly up at pixel 100 and for the thrid file it is at pixel 900. So the patterns moves around and it not always on the entire array. For the fourth file when the temperature reads -400 the saw tooth pattern goes away. But now there are large sin waves showing up in the wavelength direction. VERY odd. These large sin waves continue until the last dark file where the data looks more normal.
The very last graph is a different type of graph. In the previous images there where large sin waves in the blue "wavelength" lines on the day06 -40C data. And when looking at the image there are short "line" north to south on the images. My guess was that these "lines" are because the sine waves are moving a lot. The the last graph shows the same wavelength direction darks (blue lines in the previous graphs) but for collumns right next to each other. This for the day06 the forth dark file, temp at -40C. I am plotted the 500:505 wavelength columns. The top panel is all the lines and the 5 panels below shows each line individually. Very interesting.
